In real life, I missed a visualization of the TCP Windowsize parameter over
time which is essential when troubleshooting poor performance over an LFN. 

It can be used to easily detect if the TCP stack is working properly and
automatic adjustment of the window size. With this you can also easily detect
if there is a bottleneck in one end local performance. This helps alot to
narrow the problem having with "slow performing data transfer".

Therefore I want to extend the set of TCP Graphs with a new one that displays
the Windowsize value over time.
